Admit it ? back in the day, you were totally envious of that kid who sported an "I'm a Pepper" T-shirt. Now, thanks to folks who purge their clothes from yesteryear, you can finally get your hands on one at That 70s Shop ? if you stop in at the right time. Although the name evokes memories from the decade of platform shoes, gaudy fabric patterns, polyester pants and big collars, the shop is a vintage oasis filled with styles from the past 50 years ? some of which are making a comeback. And you can't help but love the reasonable prices and the friendly, knowledgeable staff. All things considered, That 70s Shop is one groovy trip into the past ? without any of the nasty side effects.
